Gas detector PCE-WMM 100
Warning device for carbon dioxide and oxygen / Adjustable alarms / 4-digit LC display / Consists of main and remote unit / Relay contacts / Analog output
The CO2 detector PCE-WMM 100 consists of a main unit and a remote unit. It is used to measure carbon dioxide and oxygen at a fixed location. Therefore, it warns of odorless CO2 concentration and also of low oxygen content in the air. The measured values are displayed on an LCD screen. The detection unit has two relays that can be connected to lights for visual alarm indication or speakers. Additionally, it features a built-in acoustic alarm, which emits an 80 dB sound signal depending on the gas concentration.
The warning device is used anywhere CO2 may be released. This can be in warehouses, breweries, wine cellars, or restaurants. The main unit is partially waterproof with an IP54 sealing class. Four LED indicators provide information about the system status.
